Good heavens, guys, hypering film is a common, common thing in astronomical
circles. The gear to do it is easily available, for the film can be
purchased already hypered. This is commonly used in conjunction with a
"cold" camera -- chilled down with dry ice.
Pick up an issue of Sky & Telescope and check it out. Most emulsions,
including Fuzzy's slide films and Tech Pan, are available hypered.
